7 '0 all whom it may concern:

Be it known that I, ARPAD S. MALoosAY, a citizen of the United States, residing at- Miami, in the county of Ottawa and State of Oklahoma, have invented certain new and useful Improvements in Chats-Separators for Ore-Jigs, of which the following is a specification, reference being had to the accolnpanying drawings.

This invention relates to ore separators of the type commonly known as jiggersand in which a vertically oscillating plunger or other suitable means is used for forcing water up through ore resting upon a sieve or grate and the invention particularly relates to the detailed construction of the box which is used for separating the chats from the ore bed.

In this construction of ore separator, there are provided a plurality of cells, each cell consisting of a hutch, a grating extending over the hutch, and a chats separator dis posed at the lower end of each grating extending transversely across the grating and formed with a. plurality of slots through which the chats are forced, so as to carry the chats away from the ore bed and discharge them separately from the hutch product, and also discharge them separately from the gangue, which is discharged over the top of the separator box onto the ore bed of the next adjacent cell.

The gene a1 object of my invention is to provide means for controlling the amount of flush water which is formed into and passes through the chats separator and a further object in this connection is to proide for so controlling the amount of flush water that only a minimum amount need be used, thus making a great saving in expense.

A. further object is to reduce the amount of grate surface and thus reduce the cost of the separator or jig, and further to so direct the flush water that any sand which may work through the inlet slots of the chats separator will be discharged or flushed out with the chats and the sand cannot get into the hutch product.

Other objects will appear in the course of the following description.

Ivly invention is illustrated in the accompanying drawings, wherein Figure 1 is a transverse section through an ore separator showing my improved chats separator in section;

Fig. 2 is a longitudinal section through a separator showing a plurality of cells with the chats separator disposed in said cells;

Fig. 3 is an enlarged longitudinal section of the form of separator box illustrated in Fig. 1;

Fig. 4 is an end elevation of the outer Wall of the hutch showing the manner of locking the valve actuating rod;

Fig. 5 is a section on the line 5-5 of Fig. l;

Fig. 6 is a fragmentary face view of one of the chats separators showing the slide for adjusting the effective area of the slot;

Fig. 7 is a vertical section through Fig. 6;

Fig. 8 is a longitudinal sectional view of a modified form of the chats separator box;

Fig. 9 is a longitudinal sectional view of another form of chats separator;

Fig. 10 is a longitudinal sectional view of a further modified form;

Fig. 11 is a view of a portion of the slotted plate 31 shown in Fig. 8. 7

Referring to the drawings, it will be seen that the jig or separator as a whole is constructed ordinary jigs are and consists of a plurality of cells. Each of these cells is divided from the next adjacent cell by partitions 10 and each cell communicates at one end with a piston chamber 11, wherein is disposed a vertically reciprocating piston 12, operated in any suitable manner, the reciprocations of this piston causing the water within each cell to pulsate. Across the top 'of'each cell extends a grating 13 and the oscillation of the plunger or piston 12 forces the water up through this grating with considerable rapidity. The valuable portion of the ore being the heavier remains on the bottom of the grating, while the chats or midd lings, that is to say, the less valuable portion comprising ore or rock or waste material which adhere to each other, will be forced upward and he as a stratum on the ore bed. The lighter and waste portion which is utterly valueless, forms a third or top stratum and is carried off with the water over the partition 1% which extends above the grating and over the chats separator box which will now be described. All of the parts heretofore referred to are of any ordinary or suitable construction and form no part of my invention.

One form of the chats separator is illustrated in F ig.-3. The chats separator comrises an elongated box or casing, designated 15, which isopen along a portion of upon the face ofthe outer wall of the chats separator, one of these plates being used for each slot 16 and being vertically slotted as at 18 and the wall of the separator being provided with bolts and nuts 19, thus permitting'the gate 17 to be vertically adjusted to" control the effective width of the slot 16. Preferably each gate 17 will be formed at its upper end with an outwardly extending flange whereby it may be readily manipula-ted.

One end of the chats separator is open and discharges onto a chute 20, which in turn discharges onto a chute not shown which carries the chats to a suitable place of discharge. The bottom of the chats separator is not entirely open, as i usual with the ordinary form of chats separator, but is partially closed by a longitudinally extending web 21, the under face of which rests flat against the bars of the grating 13- and the upper face of which is downwardly inclined from the inner end of the chats separator to' the chute 20. At its inner end this web 21, which forms the bottom of the chats separator, is up 'ardly extended as at 22. This inner end of the web 21 i spaced from the rear end 23 of theseparator box. Coactin'gwith this upward extension 22 of the web-21 is a gate or valve 24:. The under face of this gate or valve is shown as downwardly and outwardly curved, so as to extend approximately parallel to the upper face of the extension 22. It will be seen that when this gate door valve 2st is shifted inward, it will. close against the face of the extension 22 and whenshifted outward, a passage will be left between the extension and the gate. This gate is illustrated as being mounted upon'a longitudinally extending rod 25, which is in turn" disposed in suitable guides 26, and the rod 25 extends out through the outer end of the separator box and is there formed with a suitable handle 27. Means are to be provided for holding' the rod 25 in any ad]usted position and to this end I have shown the rod 25 as notched as at 28 and engaged by a latch 29. Thi latch, as illustrated in Fig. 5, consists of an eccentric disk and the notches in the handle engage over the adjacent wall and the dislnwhen turned in one position, binds the handle into engagement with the wall. The disk is formed with an outwardly projecting lug 29, constituting a handle whereby the disk may be manipulated. Any other suitable fastening device, however, may be used.

In Fig. 3, I have shown the web 21 as being formed with cross rows of upwardly and outwardly discharging passage 30, the

passages gradually contracting in. cross sectional area, as they extend upward, and gradually curving upward and toward the discharge and of the separator box, the discharge ends of these passages being practically parallel with the surface of'the web or bottoin 21., so that water discharged throughthese passages will be directed in jets toward-the discharge endof the separator. It will be seen that the upper face of this web2'1 is disposed beneath the line of the slots 16.

In Fig. 8, I show another form of this construction. In this case, the web 21 has the upward and rearward extension 22', as

previously described, which coacts with the gate 24, which operates inthe manner previously described. The only difference between the construction shown in Fig. 3'

and that shown in Fig. 8, is that in the last named figure the passages 30 extend upward and forward at a slighter inclination than in Fig. 3, and do not extend forward at theirupper ends, but discharge against the face of a' slotted plate 31, the upper face of the web- 21 being recessed to receive this plate 81. V

In Fig. 9, I show still another form of the separator box, wherein the web'21 is imperforateand not formed with any passages, so that the water forced upward by the pulsations of the piston or plunger pass upward through the rear end" of the plate between the rear end of the plate and the wall of the separator and then around the extension 22 and the valve or gate 24;. Otherwise than this, the construction illustrated in Fig. 9 is the same as heretofore described.

In Fig. 10, I show still another form of the separator box, wherein the bottom or.

web 2 F at its rear end is upwardly and rearw'ardly rounded as at 32', so as to form a downwardlyflaring openingorniouth for theseparator box. The extension 22 in this case extends straight upward, but is spaced from the upper wall of the box and the rear end wall. The upper face of the web 21 is (lOWllWtllLllY inclined toward the discharge end of the box and disposed above the upper face ofthe web 21' is a web 33 which is of the full width of the box and extends longi passage between the extension E22- and the flange 34 is a valve plate 36. This valve plate is formed with slots 37 which approximately coincide with the slots 35 in the web 33 and the valve plate at its forward end is upwardlyturned as at 38 and is connected to the operating rod 25. A spring 39 is preferably attached to the rear end of the plate 36 and forces it firmly down upon the upper face of the web 33. It will be obvious now that by shifting the valve plate, the effective area of the slots 35 can becontrolled. It is to be understood that the openings or slots 37 of the valve plate are so ar ranged that when the passage between the extension 22 and the flange 34 is wide open, then on shifting the valve plate outward, the passage 35 will first be opened and then the passage 35 will be successively opened,'thus giving added impetus to the constantly discharging chats.

In the last named instance the water is forced upward into the rear end of the separator box upon a depression'of the "piston or plungerand thewater flows downward through the passage between the up ward extension of the web 21 and the web 33 and this water, if the openings 35 be opened, will be forced downward to assist in forcing the chats out of the separator. By shifting thevalve plate rearward, thearea of the passage between 21 and theweh' 33 the other constructively thick head, there being enough fall in" the length of the chats separator under these i conditions so that all of the flush water necessaryis allowed to enter at the rearend' of the separator box, there being no necessity for-permitting water to enter between this rear end and the discharge end of the box.

While the various constructions which have been heretofore described differ in details, they all have thesame underlying and basic principle of water control atithe inlet "for the water and not at the outlet thereof. In all forms of chats separators known to me, the control has been at the outlet or discharge end and this merely dams the mineral back and there is virtuallyno water regulation whatever. By controlling the amount of the flush water, I minimize the use of the water and consequently secure a great saving and expense. I secure by the. use of my invention, a considerable increase in the effective grate sur face because of the narrowness of the chats Furthermore,

separator. It will be seen that the ordinary clrats separator reduces the effective area of the grate surface to an amount equal to the area of the base of the chatter resting on the grate. Practically all chatters areat least eight or ten inches wide and therefore take up 240 square inches of grate surface reducing the effective. area of the grate surface some 20%. My improved chats separator is about 2 wide and therefore it only covers an area of 60 square inches and reduces the efiective area of the grate only about 5% and therefore it will be obvious that with my chats separator, the effective area of the grate is increased. Furthermore, it is ob vious that should any sand work through the slots 16, it is flushed out by the chats and cannot get into .the hutch product. The main point of this invention resides in the control of the flushing water and in providingmeans'preventingfthe sand from working down into the hutch product. p

T-While I have illustrated a construction which I have found to be particularly effective in the concentration-of lead and zinc sulfide, it will be obvious that many minor changes might be made, without departing from the spirit of the invention.
